Parametric Tracer

Directions

This interactive applet demonstrates how parametric equations work.
You can enter an arbitrary parametric by entering the component functions at the top left.
You can then trace various values of each function by clicking and dragging on the graphs.
To turn off this feature simply disable the trace feature at the top left. You can also enter
your own ranges for t, x, and y. To see the graph being drawn click the
ANIMATE button. You can also set your own Δt by unchecking the AUTO checkbox. If you have
your own Δt set then when you trace the graph the tracer will jump discretely in Δt intervals.
